"Atlas" is a song by British rock band Coldplay for The Hunger Games: Catching Fire – Original Motion Picture Soundtrack, the soundtrack to the 2013 American science-fiction adventure film The Hunger Games: Catching Fire. It was released digitally as the lead single from the soundtrack on 6 September 2013 worldwide, and on 8 September in the United Kingdom. The song was accompanied by a lyric video, which also premiered on 6 September.

"Atlas" has charted in 16 countries and reached top ten positions in three of them, and has also received mostly positive reviews from music critics. The ballad, winning the Hollywood Song Award at the 17th Hollywood Film Awards, was nominated for a Grammy Award for Best Song Written for Visual Media and a Golden Globe Award for Best Original Song.

"Atlas" was Coldplay's first new track in almost two years, as the band's fifth studio album Mylo Xyloto had been released in October 2011. The song was written in early 2013, at the beginning of the recording sessions for the band's sixth studio album Ghost Stories, and recorded between April and July at the Beehive, one of the band's two studios in London. The sound of "Atlas" was influential in shaping that of Ghost Stories and Coldplay had originally considered including the track on the album, but it was ultimately left out of the tracklist. "Atlas" is not the first musical piece Coldplay have written for a film, but it's the first one the band has released exclusively as part of a soundtrack, without re-using it for any of their following studio recordings. The song "We're a Team" from the same movie score is also co-written by Coldplay, and features elements of "Atlas".

"I have great respect and admiration for Coldplay, and we are thrilled with how well they have connected to the themes and ideas within the film. Their unwavering passion and excitement for the project elevated the collaboration even further, and we can't wait to share this music with audiences around the world," said the film's director Francis Lawrence. "We are so honored that Coldplay, one of the iconic rock bands of our generation, will perform the first song out on the new soundtrack. Knowing that Chris Martin is a fan of the books makes this even more meaningful. The Coldplay single underscores the stature of recording artists we've assembled for this powerful soundtrack," added Tracy McKnight, Lionsgate's Head of Film Music.

The song was written by all band members and produced by Rik Simpson (with whom the band has previously worked on Viva la Vida or Death and All His Friends and Mylo Xyloto), Daniel Green (Mylo Xyloto) and Coldplay themselves.

The song is a down-tempo ballad, featuring a delicate piano refrain with a "moody, haunting melody", and showcasing Martin's lower-register vocals. According to some reviewers, it sounds "less like more recent Coldplay tracks and more like a throwback to their sound on A Rush of Blood to the Head," and "like a tossed-off remnant from the outfit's early days, before it began experimenting with deep rhythms and vivid textures." The piano builds to a bolder, "anthemic-quality" chorus with richly layered production, reminiscent of the band's fifth studio album, Mylo Xyloto.

Catching Fire's major themes informed the song lyrics, with multiple references to recurring elements of the story as well as to mythology and spirituality. According to Billboard magazine, "the lyrics abstractly touch upon main characters Katniss and Peeta's mutual reliance."

Upon release, "Atlas" received mostly positive reviews from music critics. Michael Nelson of Stereogum called the track "a swooning, appropriately cinematic ballad". Erin Coulehan of Rolling Stone wrote, "The dreamy tune features a classic Coldplay presentation, with twinkling piano that builds as Chris Martin croons 'I'll carry your world'". "The dreamy, piano-driven track was clearly written specifically for 'Catching Fire,’ with lyrics like "some bend the bow" — about bow-and-arrow-wielding heroine Katniss, presumably – and "caught in the fire" (pretty self-explanatory)," wrote Karen Lanza of PopCrush.
